Oh!!! I got it -- thanks to Kay's hint. I'm really dumb at these kind of puzzles. You know I am spatially challenged, I don't know if that has anything to do with it. Good one Pete! A year ago I had know idea of what they are. I still don't use them much. All this tech knowledge has to settle down in my brain before I add any new concept. It takes a while.Glad to see AJ has found you.

About Me

Happily married, retired. The name SNAFU was accidental, I got cross with Blogger because my name is so commonplace any variation I could think of was already in use. Computer systems do not do sarcasm and so it accepted my comment as my user name. I am not hiding my identity, my name is Pete Morris. Lifelong geek and technophile. Bookshelves in nearly every room of the house, from Blyton to Einstein. Spent most of my working life training adults in geeky stuff, from basic electrics to computer systems. My heroes are, amongst others, Richard Feynman, Freeman Dyson and Eric Laithwaite and if you don’t need to look them up in Wikipedia then you are my kind of geek. .
